This pivot was, in many ways, a good thing: it increased survival rates from infectious diseases and gave us longer lives on average. But it had one particularly negative consequence: doctors began to question whether illnesses they could not readily measure on tests were real. They doubted the testimony of those with amorphous illnesses such as autoimmunity, ME/CFS, or fibromyalgia, for which there is not always an easy test, an identifiable cause, or an effective treatment.
